Well, we're off tomorrow on our first DIY and we really didn't feel we had any option - we are a family of 2 adults and 5 children - 4 boys aged 13-15 and a girl aged 12 so we have to pay full price for them on pretty much all package deals now; can't find hotels to fit us all in and villa packages work out very expensive IMO. So I bit the bullet and decided to go DIY. I have booked a beautiful villa to sleep 7 in the Jalon Valley Spain with a prviate pool and one acre of private gardens - booked direct with owner for just over £700 for the week. We have flights booked and paid a little extra to go from our local airport but still less than £1000 for the 7 of us and then have arranged car hire direct too and we have an 8 seater booked for just over £200 for the week. So we have a wonderful week planned in our own private villa with car and flights for less than £2000 effectively for 7 adults - I think that's pretty good value but more importantly, we staying exactly where we want to stay, flying from where we want, at the time we want plus it's been great fun doing all the research.
Just back from Kenya 3 weeks ago too and did many elements of this (safaris etc) DIY but booked the flights and hotel in a package and have realised how much easier and cheaper it would have been if I had booked direct!
Got the bug now - just booked a DIY weekend in Brussels yesterday and in throes of arranging a DIY weekend for New Year in Paris, a week in Las Vegas in June 06 and all 7 of us in Orlando for 2 weeks next August...it's so good to have all the additional flexibility that you get with DIY and thanks to this site, it makes the researching very much easier.
Will let you know how this first one goes!!!
